Commonwealth Avenue Bridge Replacement Project

Commonwealth Avenue Bridge Replacement Project

Between July 26th and August 11th 2018, MassDOT will finalize the Commonwealth Avenue Deck Replacement Project, replacing the westbound side of the bridge that crosses over I-90 (Massachusetts Turnpike). There will be a "dry run" of the traffic logistics from June 1-June 3 that will reduce lanes on I-90 between the Allston Interchange and Beacon Street Overpass.

This project will reduce the number of lanes on I-90 and affect entry and exit points to I-90 in Allston; it will close the BU Bridge and Commonwealth Avenue between Kenmore Square and Packard's Corner to all traffic except MBTA buses, pedestrians, bicycles, and emergency vehicles (local business and residential traffic will be permitted on Comm Ave). Transit service will also be impacted by detours and shuttle bus options will be provided.

Significant traffic disruptions are expected and commuters using these travel options should expect delays. See the FAQs below for a more detailed list of impacts.

Commuting Suggestions:

  • Use Transit - if you normally drive to campus, consider driving to an MBTA station and using transit instead, and use the Harvard shuttle system, including the M2 if possible. Preview a route now to see what could work for you and reach out to CommuterChoice if you need some ideas. Download the Transit app for your smartphone to recieve real-time updates.
  • Walk - depending on your commute route, walking could be your fastest option; even if you take transit, walking to/from a stop could save you time if traffic gets congested. You might find an interesting route from WalkBoston's walking maps. The project area will remain open to pedestrians.
  • Bike - pedal past the congestion! The project area will be open for cyclists, and with reduced vehicular traffic this could be a good opportunity to try a new route. Use the free Park&Pedal lots if you live too far to bike all the way, and try BlueBikes (formerly known as Hubway) if you don't own a bike but can access a station.
  • Drive with others - if driving is your only option, share the ride with another Harvard driver to help keep the number of cars on the road to a minimum. Register with Zimride and Bay State Commute to be connected with nearby commuters. 
  • Adjust your work schedule - if possible, try arranging your work schedule to start earlier or later, a compressed work week (hours are worked in fewer days), or work remotely. The Office of Work/Life has great resources to help you and your manager discuss terms of a flexible work arrangement.
  • Ask Us! The CommuterChoice team can provide individual suggestions for you - just use our Personalized Commuting Assistance form to get the conversation started.

If you normally drive to campus by…
 

  • Travelling to Cambridge/Allston from the west on I-90: eastbound Exit 18 to Cambridge Street is expected to remain open; however, delays due to increased traffic and congestion should be expected. 
  • Travelling westbound on I-90 from Allston: The I-90 wesbound on-ramp is expected to remain open; however, delays due to increased traffic and congestion should be expected. 
  • Travelling from the east on I-90 (or north on I-93 to I-90) and use the Allston exit: Exit 20 will be closed intermittently. From I-90 westbound, continue to Exit 16 (Rt 16 W Newton/Wellesley) and follow signs to access I-90 eastbound. Continue on I-90 eastbound to Exit 18 (Brighton/Cambridge) and use the eastbound off-ramp to exit onto Cambridge Street.
  • Travelling eastbound on I-90 from Allston: The I-90 Eastbound on-ramp from Cambridge Street/Soldiers Field Road will be closed. Use the I-90 westbound on-ramp to continue onto I-90 westbound, then take Exit 16 (Rt 16 W Newton/Wellesley) and follow signs to access I-90 eastbound.
  • Travelling from the south (via Jamaicaway, Riverway, Rt 9, etc.) and you normally cross the BU Bridge as part of your commute: both the BU Bridge and Comm Ave closures will likely affect your route and you should refer to the MassDOT detour map for suggested options.
  • Traveling from the north on I-93 or Rt 1 and usually take Storrow Drive inbound and outbound: expect heavier than usual traffic and delays and consider alternative routes.

If you walk, run or bike, here are some additional points to be aware of:

  • Two-way access for pedestrians and cyclists will be maintained across the BU Bridge and along Commonwealth Avenue during the project; however, significant travel disruptions are expected and if you normally bike or walk to campus, please be aware of traffic patterns around you as they may change due to the construction. 
  • Refer to the MassDOT detour map for bike and pedestrian detour routes around the construction area
  • Blue Bikes (formerly known as Hubway) provide an option for short bike trips
  • Memorial Drive is scheduled to remain open to vehicular traffic on two Sundays during this project (July 29 and August 5)
